How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://defi-yield.agentdiet.dev/v1/context-compress)
Output
Returns a JSON object with the distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), an roi_proof block showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd, plus optional cache hit/miss status and billing details.
Example use cases
Compress docs into agent context window
“Distill https://openai.com/pricing into structured mode so I can see the pricing tables cleanly — I need it compact enough to fit in my context window.”
BM25 excerpt for research query
“Grab https://en.wikipedia.org/wiki/Transformer_(machine_learning_model) and give me only the parts relevant to 'attention mechanism' in budget mode, capped at 500 tokens.”
Convert raw HTML to clean Markdown
“I have a raw HTML blob from a scraped product page — can you distill it into markdown mode so I can pass it cleanly to my summarization agent?”
Technical details
Endpoint
POSThttps://defi-yield.agentdiet.dev/v1/context-compress?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to ingest a webpage or HTML blob while strictly controlling token consumption — especially in agentic pipelines where context windows are finite. The BM25 budget mode is uniquely suited for query-focused extraction from long documents. Prefer it over generic scrapers when you need provable token savings (roi_proof), multiple output modes (markdown/structured/skeleton/budget), and built-in cost accounting.
Side effects
- URL is unreachable or returns non-200 response — fetch error returned
- html field omitted and url field missing or empty — validation error (url is required)
- max_tokens set below 20 — schema validation rejection
- Target page blocks scraping (403/captcha) — distillation fails or returns partial content
- query field absent when mode=budget — BM25 scoring may fall back to default ranking
- Token budget too small for meaningful extraction — truncated or empty excerpt
